Most European countries alongside the UK will need to turn their clocks forward by 1 hour this Sunday, 29 March 2026. While you enjoy the sun and longer days, you will also need to check that the time settings in your trade/transaction reporting are correct.
Here are TRAction’s two tips to help you ensure your trades/transactions are reported at the correct time
1. Check the Time fields in your handback files
The first day that you receive handback files for trades/transactions carried out after the commencement of daylight savings will be Tuesday, 31 March 2026.
If your market is closed on Monday, 30 March 2026 (e.g. Malta), the first day you receive handback files after the time change will be Wednesday, 1 April 2026.
Either way, it’s important to do the following check and act promptly if there is any problem.
You will need to cross-check the time of your trades/transactions against the UTC time recorded under the following LSEG Regulatory Reporting and DTCC fields:
EMIR and MiFIR
You will need to cross check the time of your trades/transactions against the UTC recorded under the following LSEG Post Trade Repository (TR) and Approved Reporting Mechanism (ARM) fields:
- MiFIR – Trading Date Time field
- EMIR – Execution Timestamp field
SFTR
You will need to cross-check the time of your trades/transactions against the UTC recorded under the following DTCC fields:
- SFTR – Execution Timestamp field
How to check?
- Select a sample of trades from your raw data and convert the time to UTC; and
- Compare those against the UTC populated under the fields as described above in your handback files.
If the time does not match, please contact us.
2. Check time recorded for daily snapshot (if applicable)
For firms that submit a daily snapshot for trade/transaction reporting, double check that it is occurring at the intended end-of-day time.
Completing these checks helps avoid corrective submissions and minimises the risk of future breaches.
If you have any concerns or are not sure how to do this check, please contact us.
